I installed a brake cable/housing on my TT bike (Vision bar) and every time I hit the brake lever and release it, the cable end comes out of the lever... I checked cable tension and that doesn't seem to be the issue, no slack there. The only thing I can think of is that the housing angle that goes from the basebar to the stem, which also has a barrel adjuster in the middle, might be too sharp. Could that be the reason for what is happening?

I'd like somebody's opinion on this before I take the housing apart and re-do it since I would need longer housing. Anybody experienced that before?
